The `MessageCollection` would give a pending message to `onMessagesAdded` where every pending message has a message ID of zero. Then when the message is sent successfully or failed sending, it gives an event `onMessagesUpdated` to update the message. In that case the message ID is set to the actual ID if succeeded. (And stays zero if it fails)

It’s designed by nature that a pending message is to preview the message before being sent, then updated to a succeeded message. If you’re rendering messages with a unique key, you can refer to `requestId` instead (succeeded messages also have it). You can check the message status with `sendingStatus` property in a message.
